The most dangerous tool in a kitchen is a dull knife.
There are a variety of honing stones, electric as well as hand held items to use in doing so.
The Japanese professional is my favorite. However it does take some skill and practice to do so. What I will often do is use the electric one to grind out any nicks and then the stone to hone the edge.
Bar Keeper Friend is a wonder product I have used for years.
This stuff is also awesome on tile floor problem areas, porcelain sinks and so many other items as well.So remember to keep a safe kitchen with sharpened knives. You can find many tutorials on line. Teach yourself this useful skill you'll enjoy good knives for a life time. Remember if they are kept in drawer to sheathe them to protect the blades. One day the dream is a nice magnetic bar on the side of the cabinet. In drawer has been the safest while my kids are younger.
